Title: Manufacture of nickel electrode for battery
Inventor: IWAKI TSUTOMU
IPC: H01M4/52
Filed: 1982-04-06
Abstract: PURPOSE:To enhance the utilization rate of a nickel electrode and extend the life of the electrode by manufacturing moistened cobalt oxide or cobalt hydroxide which is then added to an active material. CONSTITUTION:Cobalt oxide (hydroxide) is prepared from an aqueous cobalt- acetate solution and an aqueous caustic-potash solution For instance, after 250g of cobalt acetate is dissolved in 2l of water, an excessive amount of 10wt% caustic-potash solution is added to the solution so as to make precipitates. Thus obtained precipitates are washed with water by the usual filtration until almost no alkali remains. Next, the above moistened precipitates are added to an active material mixture so as to make a paste. After that, a sealed nickel-cadmium battery of the single-2 type is constituted by using the convertional cadmium electrode, a non-woven polyamide fabric used as a separator, and a solution prepared by dissolving 20g of lithium hydroxide in 1l of 20wt% aqueous caustic- potash solution as electrolyte.

Filed: 1978-05-16
Abstract: PURPOSE:To prevent the incorrectness in time due to the back-lash of a transmission mechanism by generating such compensating pulses of at least one pulse as can turn a converter forward after the converter is interrupted when the same is turned backward by the control of contact. CONSTITUTION:The output of a frequency divider 2 is fed to a drive signal generating circuit 4 so that it is displayed in a display unit 6 while driving a converter 5. A contact 3 and a compensating pulse generating circuit 7 are connected with the circuit 4. By operating the contact 3 from the outside, there are generated from the circuit 4 the drive signals which are operative to turn the converter forward or backward. When the contact 3 is operated to turn the converter 5 backward, the forward compensating pulses of at least one pulse are generated after the interruption so that the incorrectness in the time of display due to the back-lash of a transmission mechanism can be prevented.
